The Canon 7D has a 720p mode that can shoot at 60 frames per second.

Does that make it one of the best cameras in existance?

at last 25fps!!

What I couldn't find out through that article is whether you have to still freeze the aperture.....?

I think the issue of the difficulty in the practicality of pulling focus is still apparent...

but the 5d would only allow you to shoot moving images in auto mode.....has it changed with the 7d?

The article mentioned 24fps. Great stuff!

Given that they came out with a firmwire update for the 5D M2 that allows you to manually select shutter speed and aperture for the video, I would assume not; why would they make the same mistake twice? Then again...maybe I'm giving them too much credit.

" Users can set exposure and frame rate – with options for 24 fps to create that cinematic feel."

whatever that means...

Last hing I heard, the newest firmware upgrade for the 5D allows full manual controls of the camera in video mode, dunno about the 7D.

The small APC size of the sensor means this camera is not really a step forward for digital cinematography. Still, the addition of 24p/25p using the same processor chip seems to suggest that canon could soon produce a full frame model of some sort that is capable of the same useful frame rate. The 7D however uses two chips in a "dual processor" arrangement. The 5D uses only one processor.

Looking forward to the day when all companies get on the larger sensor bandwagon. The ability of the 5D to shoot in low light is astounding. Almost everything else about the camera in the context of digital cinematography is frustrating however.

This camera is a strong competitor for the nikon D90 - it shoots full HD and is in a similar price range, as I understand it.

With luck, maybe this camera proves that the 5d will be able to shoot 24/25p with a firmware update. Any guesses? it doesn't seem as though the task of shooting 24p would be split between two processors when one is capable of handling a faster rate. What DOES the second process do, anyway - is it possible to determine, or speculate?

Aha!
It was prior to that firmware update that I lost interest then.......I retract my comment.

Saul - from what you and Elliot say I should imagine that manual control would come as standard on the 7d.

Does anyone know if it this 7d has inherited the 5dII's rolling shutter problem?

The size this particular APS-C sensor (21.95 mm × 16.00 mm) is roughly equivalent to 4-perf 35mm image size (22.3 x 14.9 mm), though most APS-C sensors are size-dependent brand to brand. Why is bigger better anyway? What is wrong with smaller sensors / image areas? Does every project need to be shot on S-35 sized-imagers?

Does every camera released these days must be "a step forward" in digital camera technology, whatever that means, to be a useful camera?

Since the 5D mk II's chip size is Vista Vision-sized, must the new Canon offering be IMAX-sized to be a useful camera and "a step forward in digital cinematography"?

Help me understand, please.

Sorry, I inverted the numbers, it should read:

Hey Serge,

It says here these cams have manual controls:

"The exposure of the movie can be controlled in Manual mode allowing full control of shutter speeds and apertures. It is possible to select frame rates from: 30 (29.97), 25, and 24 (23.976), with 60 (59.94) and 50 available at 720p. ISO can be set automatically or manually in the range (100-6400) and is expandable to 12800. EOS 7D also allows users to trim and cut their movies."

http://www.dpreview....5canoneos7d.asp

I would imagine the rolling shutter is still a problem, as most CMOS chip cameras (such as this one) suffer from it to some degree or another. . . Mere speculation, of course.

Well, when you examine a digital image taken with an APS chip @ 400 ISO and see that it looks virtually equivilant to a full frame digital image taken @ 1600 ISO...you wonder why you ever used the former to begin with; at least that was my experience when I upgraded my Canon Rebel XTi to a 5D. Also you have to take into account the myriad of amateurs concerned with the all-mighty "CROP FACTOR!" :rolleyes:

completely missed that....feeling a bit dumb right now.
Thanks for the heads up Saul. ;)

I think you probably have the 4 perf Academy numbers. The 7D sensor is a little smaller than Super-35 4 perf, which is 24 x 18 mm. That's good, since you could put a PL mount on it and use all the S-35 glass that's out there.
